title = "Volumetric study of a turbulent boundary layer and swept impinging oblique SBLI at mach 2.3",
abstract = "A swept impinging oblique Shock Boundary Layer Interaction (SBLI) is investigated in Mach 2.3 flow induced by a shock generator with sweep ψ = 30.0° and x-y plane deflection of θ = 12.5°. The incoming flow is a naturally turbulent boundary layer developing over the flat wind tunnel wall with Reθ = 5.5 × 103. A combination of Stereo PIV and Tomographic PIV is used to characterize both the undisturbed incoming boundary layer and the resultant complex geometries of the swept SBLI. Linear Stochastic Estimation is used to identify statistically significant boundary layer vortical structures and document changes to their topology at various heights in the boundary layer. Three-dimensional velocity snapshots throughout the swept SBLI show both large-scale growth/collapse of the interaction and prominent streamwise streaks with a notable spanwise periodicity. Finally the mean structure for this configuration is documented for the first time. This is an initial summary of a large PIV data set (over 3 TB) that already provides a valuable contribution to the understanding of this complex flow.",
